Abstract
Configuration changes are dynamically applied to a cluster multiprocessing system by enqueuing a configuration change event. When the configuration change event is processed, the prior configuration is backed up and each software component applies a relevant portion of a configuration change transaction in an ordered, synchronized manner. Each software component applies its portion of the transaction either by reinitialization or a logged transition operation. If the configuration change transaction fails, the software components roll back the portions, of the configuration change already applied in an ordered, synchronized manner to restore the prior configuration. Multiple events for different configuration changes may be enqueued.
